[PATCH 21/28] video: fbdev: imsttfb: constify pci_device_id.

From: Arvind Yadav
Date: Thu Jul 20 2017 - 13:41:22 EST


pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

File size before:
text data bss dec hex filename
6736 856 0 7592 1da8 drivers/video/fbdev/imsttfb.o

File size After adding 'const':
text data bss dec hex filename
6832 760 0 7592 1da8 drivers/video/fbdev/imsttfb.o
